Get notes related to a specific note. Returns outgoing links (notes this note links to) and incoming links/backlinks (notes that link to this note). Supports depth traversal and content snippets.
AI agents call get_related_notes to retrieve information from Obsidian MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and retrieves relational metadata (links) and optionally displays content snippets from related notes. It has no side effects on data—no creation, modification, deletion, or code execution. The blast radius of misuse is minimal: an agent could only traverse and read existing note relationships and snippets within the vault structure already visible to authorized users.
From the tool's definition Tool returns outgoing and incoming links related to a note, with optional depth traversal and content snippets. No modification, deletion, or execution occurs. Description explicitly indicates retrieval of link relationships and related note information.
Attacks that exploit this kind of access
Get notes related to a specific note. Returns outgoing links (notes this note links to) and incoming links/backlinks (notes that link to this note). Supports depth traversal and content snippets. It is categorised as a Read tool in the Obsidian MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Obsidian MCP Server MCP server in PolicyLayer and add a rule for get_related_notes: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Obsidian MCP Server. Nothing to install.
get_related_notes is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_related_notes rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_related_notes. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_related_notes is provided by the Obsidian MCP Server MCP server (senseibas/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
